Apprehend in Tintern Abbey (3)
I believe the answer is:
nab
'apprehend' is the definition.
(I know that apprehend can be written as nab)
'in tintern abbey' is the wordplay.
'in' says the answer is hidden in the clue.
'NAB' is hidden in the letters of 'tintern abbey'.
(Other definitions for nab that I've seen before include "Catch (a felon)" , "Catch (thief) (colloq.)" , "nail" , "Apprehend" , "Run in" .)
